B A N I S T E R I A A JOURNAL DEVOTED TO THE NATURAL HISTORY OF VIRGINIA ISSN 1066-0712 Published by the Virginia Natural History Society The Virginia Natural History Society (VNHS) is a nonprofit organization dedicated to the dissemination of scientific information on all aspects of natural history in the Commonwealth of Virginia, including botany, zoology, ecology, archaeology, anthropology, paleontology, geology, geography, and climatology. The society’s periodical Banisteria is a peer-reviewed, open access, online-only journal. Submitted manuscripts are published individually immediately after acceptance. A single volume is compiled at the end of each year and published online. The Editor will consider manuscripts on any aspect of natural history in Virginia or neighboring states if the information concerns a species native to Virginia or if the topic is directly related to regional natural history (as defined above). Biographies and historical accounts of relevance to natural history in Virginia also are suitable for publication in Banisteria. Membership dues and inquiries about back issues should be directed to the Co-Treasurers, and correspondence regarding Banisteria to the Editor.

ABSTRACT A three year (2017-2020) inventory at the Smithsonian Environmental Research Center, Edgewater, Anne Arundel County, Maryland resulted in 23 species in nine families: Buprestidae- 6, Callirhiphidae- 1, Cleridae- 3, Dermestidae- 2, Eucinetidae- 2, Histeridae- 2, Melyridae- 1. Ptinidae- 5, and Trogossitidae- 1. Eucinetus morio LeConte and Nycteus testaceus (LeConte) (Eucinetidae) are reported for the first time in Maryland. Keywords: Biodiversity, insects, Maryland. INTRODUCTION This section of the annotated checklist contains the species from a miscellaneous group of Coleoptera families in various superfamilies and functional groups which were not speciose enough to warrant separate treatment. Buprestidae, metallic wood boring or jewel beetles, larvae burrow in roots and logs, within the bark or cambium layers of trees and shrubs or are leaf or stem miners of herbaceous or woody plants. Most species attack dead or dying branches while a few attack healthy wood. There are more than 14,600 described species worldwide with 762 species from the United States & Canada (Bellamy & Nelson, 2002). Steury & MacRae (2012) reported 25 species from a six year inventory at the George Washington Memorial Parkway (Fairfax, Virginia). The Maryland Biodiversity Project (MBP) (2021) reports 98 species from Maryland. 102 Staines & Staines / Banisteria 55: 101–111 (2021) Callirhiphidae is a small family of 16 species worldwide with one species, Zenoa picea (Beauvois), known from the United States. Larvae are found in rotting wood usually with fungi. Adults are short-lived, active at night, and are attracted to lights (Young, 2002b). Staines (1983) reported Z. picea from three counties in Maryland. The Maryland Biodiversity Project (MBP) (2021) reports this species from six Maryland counties. Cleridae, checkered beetles, are mostly predaceous as larvae and adults. They are often found on woody plants or under bark, in galls, or on plant foliage. Some species are important predators of bark beetles. There are 3366 described species worldwide with 291 in the United States and Canada (Opitz, 2002). Steury & Leavengood (2019) reported 18 species from a 19 year inventory at the George Washington Memorial Parkway (Virginia). The Maryland Biodiversity Project (MBP) (2021) reports 23 species from Maryland. Dermestidae, skin beetles, are scavengers on dried animal or plant material with a high protein content. Larger species are found on carrion in the late (butyric) stage, while smaller species are found in bee and wasp nests feeding on pollen stores. Some species are serious pests of stored products. There are approximately 700 species known worldwide with 123 species in the United States (Kingsolver, 2002). The Maryland Biodiversity Project (MBP) (2021) reports six species from Maryland. Eucinetidae, plate-thigh beetles, live in detritus or under fungus-covered bark of trees. Larvae feed on fungi, slime molds, or mushrooms. There are 37 known species worldwide with 11 species known from the United States and Canada (Young, 2002a). The Maryland Biodiversity Project (MBP) (2021) does not report species from Maryland. Histeridae, clown beetles, are mainly predators on soft-bodied insects and eggs, especially of flies (Diptera). Beetles are found in substrates on which flies develop in numbers, the dung of mammals, mammal and reptile burrows, carrion, rotting vegetation, rotting fungi, and fermenting phloem and cambium of dead hardwoods. There are about 3900 species known worldwide and 435 from the United States and Canada (Kovarik & Caterino, 2000). The Maryland Biodiversity Project (MBP) (2021) reports 17 species from Maryland. Melyridae, soft-winged flower beetles, adults appear to be phytophagous, mainly on pollen. Other species are omnivorous scavengers or predators on small arthropods. Larvae are poorly known. There are about 6000 species worldwide with 520 species in the United States and Canada (Mayor, 2002). The Maryland Biodiversity Project (MBP) (2021) reports six species from Maryland. Ptinidae, death watch and spider beetles, larvae bore into bark, dry wood, twigs, woody fruits, galls, and fungi. Other species feed on dried animal and plant material and are common in bird or mammal nests. Some species feed on pollen in bee nests (Hymenoptera) or are found in ant nests (Hymenoptera: Formicidae). There are more than 2200 species known worldwide with 464 species in North America (Philips, 2002). The Maryland Biodiversity Project (MBP) (2021) reports 10 species from Maryland. Trogossitidae, bark-gnawing beetles or cadelles, are predatory or have an unknown biology. They can be found under bark or in the galleries of wood boring beetles. A few species are found in fungi. There are about 600 species known worldwide with 59 species found in the United States and Canada (Leschen, 2002). The Maryland Biodiversity Project (MBP) (2021) reports six species from Maryland. SERC Coleoptera: Miscellaneous Families 103 MATERIALS AND METHODS The Smithsonian Environmental Research Center (SERC) [38°53’13”N; 76°32’21”W] consists of approximately 1477 ha of hardwood-dominated forest, ponds, creeks, rivers, tidal marshes, and 19.3 km of shoreline along the Rhode River and upper Chesapeake Bay in Anne Arundel County, Maryland (SERC, 2018). Forests on the main campus of SERC can be broadly classified into three main types: (1) the majority (~85%) is a Tulip-poplar (Liriodendron tulipifera L., Magnoliaceae) association; (2) a moist lowland assemblage, comprised of American sycamore (Platanus occidentalis L., Platanaceae), ash (Fraxinus spp., Oleaceae), elms (Ulmus spp., Ulmaceae), river birch (Betula nigra L., Betulaceae), and other woody vegetation along freshwater streams; and (3) a semi-xeric assemblage that fringes tidal marshes, consisting of chestnut oak (Quercus prinus L.), white oak (Quercus alba L., Fagaceae), black gum (Nyssa sylvatica Marshall, Nyssaceae), mountain laurel (Kalmia latifolia L., Ericaceae), blueberries (Vaccinium spp., Ericaceae), American beech (Fagus grandifolia Ehrh., Fagaceae), and other woody vegetation (McMahon et al., 2010; Higman et al., 2016). Like much of the eastern United States, SERC’s forest age and structure reflect historical agricultural activities and local history. SERC’s main campus was mostly fallow from the end of the Civil War (1865) to approximately 1915, when it was used as a dairy farm with grazing pastures and fields for feed production until 1945. Thus, the majority of SERC’s contemporary forests are from 70-150 years old (McMahon et al., 2010; Higman et al., 2016).
